Display Panel Time Division Multiplexing for High Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels often face challenges in displaying high-resolution images due to lower resolution capabilities, leading to partial image display or loss of pixel details, which affects user experience.
Innovation Solution
The display method involves dividing pixel units into odd-numbered and even-numbered display groups, with each group displaying alternate frames of images with specific resolutions, allowing for time division multiplexing of sub-pixels to enhance resolution and maintain richer details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If pixel sampling is used to display complete image on lower resolution screen, then image completeness is improved, but image detail quality deteriorates
Solution Approach 1:
The pixel units are divided into odd-numbered and even-numbered display groups, with each group containing specific sub-pixels (first, second, and third sub-pixels). This segmentation allows different groups to display different frames alternately, enabling the display panel to show complete high-resolution images without losing detail quality by utilizing temporal multiplexing of the segmented pixel groups.
2Manufacturing precision
If partial image display is used to maintain pixel quality, then image detail quality is improved, but image completeness deteriorates
Solution Approach 1:
The odd-numbered and even-numbered display groups alternately display different frames in a periodic manner. The odd-numbered group displays odd-numbered line images while the even-numbered group displays even-numbered line images, creating a temporal multiplexing effect that presents the complete high-resolution image to the user over time, thereby maintaining both image completeness and detail quality.
3Loss of information
If display resolution is increased to show complete high-resolution image, then image completeness is improved, but device complexity increases
Solution Approach 1:
Each pixel unit is designed with multiple sub-pixels (first, second, and third sub-pixels) that can serve different functions depending on the frame being displayed. The same physical pixel structure is used to display both odd-numbered and even-numbered line images by activating different sub-pixel groups, making the display panel multi-functional without requiring separate physical structures for different resolutions.

AI summary
A display method comprises: acquiring multiple frames of images to be displayed, one frame of two adjacent frames of the images to be displayed being an image in an odd-numbered row, the other frame being an image in an even-numbered row, the resolution of the image in the odd-numbered row being M*(a*N), the resolution of the image in the even-numbered row being M*(a*N) or (M−1)*(a*N), and a being 1 or 2; and causing an odd-numbered display group to display the image in the odd-numbered row, and causing an even-numbered display group to display the image in the even-numbered row, the odd-numbered display group comprising M*(a*N) odd-numbered display units, the even-numbered display group comprising (M−1)*(a*N) even-numbered display units, the odd-numbered display unit in the i-th row comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel in a pixel unit in the i-th row.
